Electro Hardware MMX1615M06-MSC Hex Standoff M4x0.7 10mm

Product Description

The ELECTRO HARDWARE MMX1615M06-MSC is a male-male hex circuit board standoff designed to create fixed spacing between printed circuit boards or between a board and a mounting surface. Machined from Grade T-3 aluminum with a clear finish, this standoff meets the QQ-A-225A Comp 2 fastener standard. The metric M4 x 0.7 thread runs on both ends, with an overall length of 10 mm and a hex body width across flats of 8 mm. Thread length ranges from 8.5 mm to 9.5 mm depending on engagement. Electricians, electronics technicians, and control board service professionals install these when assembling or servicing panel-mounted circuit boards in HVAC controls, electrical enclosures, and similar equipment.

This standoff is suited for metric M4 threaded applications requiring a rigid aluminum spacer between circuit board layers or between a board and a chassis. Common installation scenarios include HVAC control board assemblies, variable frequency drive enclosures, and industrial electrical panels where a lightweight, corrosion-resistant aluminum fastener is preferred over steel. The hex body shape allows wrench engagement for controlled torque without slipping. At 0.16 pounds per package, handling and positioning on tight board layouts is straightforward.

Key Features

• Male-male thread configuration on both ends for board-to-board or board-to-chassis spacing
• M4 x 0.7 metric thread size with thread length range of 8.5 mm to 9.5 mm
• Grade T-3 aluminum construction — lightweight and corrosion resistant
• Hex body shape (8 mm width across flats) allows standard wrench or nut driver engagement
• Clear finish per QQ-A-225A Comp 2 standard
• 10 mm overall length suits compact PCB stack configurations

Compatibility

Designed as a direct-fit metric standoff for applications using M4 x 0.7 threaded hardware in circuit board assemblies, electrical enclosures, and control panel builds.

Installation Notes

De-energize all circuits and discharge any capacitors before handling circuit boards or installing standoffs in live control panels. Use an appropriately sized nut driver or open-end wrench on the hex body to prevent rounding or over-torquing the aluminum material. Follow NEC guidelines and any applicable equipment manufacturer service procedures when working inside electrical enclosures. Avoid applying thread-locking compounds unless the assembly specification calls for it, as removal of aluminum fasteners with adhesive can strip threads.
